STMicroelectronics has introduced the ASM330LHBG1 automotive 3-axis accelerometer and 3-axis gyroscope module with a safety-software library that enables a cost-effective solution for functional-safety applications.

The ASM330LHBG1 is AEC-Q100 Grade-1 qualified for the ambient operating temperature range -40°C to 125°C, allowing use such as next to the engine compartment and in areas exposed to sunlight. The modules deliver high accuracy and reliability for systems such as vehicle navigation, body electronics, in driver support and highly automated driving systems. Typical uses include support for precise positioning in navigation systems, digitally stabilizing cameras, lidars, and radars, and in active suspension, door modules, vehicle-to-everything (V2X) applications, adaptive lighting, and motion-activated functions.

Equipped with ST’s machine-learning core (MLC) and programmable finite state machine (FSM), the ASM330LHBG1 can run artificial intelligence (AI) algorithms in the sensor to provide smart functionality at very low power. This IMU is pin-to-pin compatible and shares the same configuration of registers as ST’s automotive IMUs with a lower operating temperature range, permitting a seamless upgrade.

In addition, the modules contain embedded temperature compensation, which ensures stability over wide-ranging operating conditions, and provide a six-channel synchronized output to enhance the accuracy of dead-reckoning algorithms (more info).
